Truma water heater re-set button.

Hi All and Happy Easter for this weekend  .   Does anyone know where the Truma heater hot water re-set button is located.

 I am not getting  hot water out of the taps (just cold).  Plus the Truma heater body doesnt feel warm. This is after a a re-fill and hot water one way valve replace.(one of my winter jobs )

Hope you can help, Regards Chris

Chris, have you switched on the isolator switch for the hot water heater. We have 2 switches under the oven; one for the diesel/electric van  heater and another for the gas/electric water heater. My handbook indicates an automatic reset after 10 minutes. Hope this helps Jeff.

Hi Jeff, Thanks for your prompt reply  .   I have one fused switch under the oven with a red light indicating on, which seems to work .   
I didn't realise the we had auto re-set but like the idea of it.   I got the idea about re-set button from my handbook; fault finding section.  
Have to admit to being something of a motorhome virgin
